D) 70%

Question

Quizplus · Accepted Answer

Methanocaldococcus jannaschii is a hyperthermophilic microorganism that lives in deep-sea hydrothermal vents. The analysis of its genome showed that about 40% of its genes have no counterparts in known genes from other sequenced organisms, which suggests that this microorganism has unique adaptations to its extreme environment. This high percentage of unique genes is one of the reasons why this microorganism has been extensively studied and is of great interest to biologists.
